A cystogram is an x-ray study of the urinary bladder. The study places a catheter into the bladder, and is used to place an x-ray dye into the bladder. The dye allows the bladder to be viewed under x-ray fluoroscope. The radiologist will interpret the report and send the results to your doctor. Your doctor will discuss the results with you. If you are a woman of childbearing age and think you may be pregnant, please tell your doctor or the technologist prior to the test.
